IMPROVEMENT IN HYDRANTS..

The Schedule referred to in these Letters Patent and making part of the same.

To all whomI it 'may concernl Be it known that l, J Mns ALLisoN, of Cincinnati, in the county of Hamilton, and State of Ohio, have invented a new and useful Improvement in Hydra-nts; and I do herebydeolare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being hadto the accompanying drawings, form# ingpait of thisy specification.

rL his invention relates to improvements in hydrants, and it consists in the construction ofthe lower portion of the discharge-pipe, arranged to operate in connection with the enlarged vertical portion o'f the water# pipe, as will be hereinafter more fullydescrib'ed.

On reference to the accompanying drawings,

Figure l. represents an elevation of my improvement, when used as a hydrant;

Figure 2 representsa vertical section of the same;

Figure 3 represents an enlarged vertical section of -the part connecting with the water-pipe, showing the arrangement of the valves;

- Figure 4, a hose, with plug for 'connection when used for washing streets, or as a fire-plug', shown in red; Figure 5,' a'dciaehable cap, to fbe substituted when it isv also to be used as a hitching-post; and

Figure 6, a view of a plate provided with a hitching- Y ring, to be attached to the post also,- when a bitching-post.

Similar letters of reference indicate corresponding parts.

A represents a hollow post, which is set into the ground,in the usual manner, for protecting the waterpipe, which is provided at the top with a detachable cap, B, having a socket, which sets over the top of the` post A, and is 'provided 'with an annular groove, into which a corresponding ridge on the post may be drawn on one sido by the setfscrew, when it isA scre'v'vedl up, whereby the cap is permanently secured with one or more setfserews.

D represents the vertical water-pipe, to which the spouts E or plugs E are connected by a detachable connection, whereby one may be readily substituted for another.

F represents a veitiwtl extension .ofthe Water-pipe G, attached to the latter by a screwed joint; and

H represents the lower portion of the vertical pipe, which is provided at its lower end with ayielding disk of rubber, which serves as a valve for opening or closing the passage of the water from pipe G, and is operated by the nut C on the top of the shaft, which is oonnected to the upper end of the-pipe D by a screwed.

connection, whereby the pipe DV may be raised or lowered to open or close the passage for the water.

The water enters the vertical pipe D through th openings b. A

d and d' represent wastepassages, and

e and e', rubber-packing rings.

The ring e is intended to prevent the passage of the water from below out at the waste-passages, and tooe raised up when the pipe D is raised to open the. pas- ,I sage at I, so as to close against the waste-passage, to prevent the water from flowing out-thereat while it is being drawn out. at the spout.

The ring e is intended stop the passage of the waste water upward.

K represents a cap, secured to the lower end yof the post A, in a manner similar to the cap, B, at the top.

A'stud, j, on the bottom of thewater-pipe G,passcs through' the said cap, and is secured to it, as shown by a nut, f'

When it is desired to use my improved apparatus as a hydrant, the curved spout E is applied, as shown in fig. 2, and when it is to be used for washing the streets, or in cases of fire, the hose-pipe, as shown in fig. 4, may be substituted, and when it is desired tc convert the post into a bitching-post, the holte-head cap, fig. 5, may be substituted for the cap, B, and a nut, C', may be applied to the head for working the valve, and made in a form similar to the nut C, or it may be provided with a small square projection to be turned'with a wrench, and the ring-plates, fig. 6, may be attached, in place ofthe ornamental figures, on the plain surfaces near the spout.

By means of the above-described arrangement of hydrants, the several enumerated purposes mayall be subserved by the same device, With but slight modiications; as, forinstance, in the general 'use of them, someare required for hydrants to be set the street, when it is also desirable to maliens/c of them 'for hitching-posts, and for washing the streets, while others may be required to be set in a Wash-room, orin a yard where they are only required as hydrants.

' Therefore, in the manufacture of them, the several parts may be promiscuously made, and put together as required.

Moreover, as an improvement in nre-plugs-over the now common arrangement of 'fire-plugs, my arrangement possesses peculiar advantages. As the former are set into tlie walk, generally' in recesses, they are more liable to get out of order,-.and to be entirely covered and frozen up in cold weather, whereas, according to my improvement, they are not exposed to such culties.

I claim as new, and desire to secure by-Letters Patent- The hollow perforated pipe H, provided with the 'elastic disk I, waste-passage d, and elastic packingringse e', arranged to operate in connection with the cylinder F, having'the waste-passage d, as herein described, lfor the purpose specified.
